Zum 80. Todestag von Dr. Walther Horn

Aus Anlass seines 80. Todestages am 10. Juli 2019 wird die Lebensleistung von Dr. Walther Horn gewürdigt. Horn war von 1909 bis 1939 Direktor des Deutschen Entomologischen Instituts. Er gehörte zu den herausragenden und bekanntesten Entomologen seiner Zeit. Im Fokus stehen seine Verdienste um die nachhaltige Weiterentwicklung des 1886 gegründeten Deutschen Entomologischen National-Museums, das Horn trotz schwieriger zeitgeschichtlicher Rahmenbedingungen zu einem international anerkannten Forschungsinstitut ausgebaut hat, und das heute als Senckenberg Deutsches Entomologisches Institut in seinen wesentlichen, von Horn begründeten Aufgaben und Besonderheiten fortbesteht. Schlaglichtartig werden Horns Leistungen als Entomologe, Museologe, Wissenschaftsmanager und Humanist herausgestellt. Zu Ehren Horns übernahm der Förderverein des Deutschen Entomologischen Instituts e. V. im Jahr 2018 die Pflege seiner Grabstätte in Berlin-Lichterfelde.On the occasion of the 80th anniversary of his death on July 10, 2019, the life’s work of Dr. Walther Horn is honoured. Horn was director of the Deutsches Entomologisches Institut (German Entomological Institute) from 1909 to 1939. He was one of the most outstanding and best-known entomologists of his time. The focus is on his services to the sustained development of the Deutsches Entomologisches National-Museum (German Entomological National Museum), founded in 1886, which Horn developed into an internationally recognized research institute despite the difficult conditions of contemporary history. This institute continues to exist today as the Senckenberg Deutsches Entomologisches Institut, carrying out the main tasks envisaged by Horn, and still possesses many of the special features with which he endowed it. Horn’s achievements as an entomologist, museologist, science manager and humanist are highlighted. In honour of Horn, the Friends of the DEI (Förderverein des Deutschen Entomologischen Instituts e. V.) took over the care of his grave in Berlin-Lichterfelde in 2018

Factors associated with diversity, quantity and zoonotic potential of ectoparasites on urban mice and voles

Wild rodents are important hosts for tick larvae but co-infestations with other mites and insects are largely neglected. Small rodents were trapped at four study sites in Berlin, Germany, to quantify their ectoparasite diversity. Host-specific, spatial and temporal occurrence of ectoparasites was determined to assess their influence on direct and indirect zoonotic risk due to mice and voles in an urban agglomeration. Rodent-associated arthropods were diverse, including 63 species observed on six host species with an overall prevalence of 99%. The tick Ixodes ricinus was the most prevalent species, found on 56% of the rodents. The trapping location clearly affected the presence of different rodent species and, therefore, the occurrence of particular host-specific parasites. In Berlin, fewer temporary and periodic parasite species as well as non-parasitic species (fleas, chiggers and nidicolous Gamasina) were detected than reported from rural areas. In addition, abundance of parasites with low host-specificity (ticks, fleas and chiggers) apparently decreased with increasing landscape fragmentation associated with a gradient of urbanisation. In contrast, stationary ectoparasites, closely adapted to the rodent host, such as the fur mites Myobiidae and Listrophoridae, were most abundant at the two urban sites. A direct zoonotic risk of infection for people may only be posed by Nosopsyllus fasciatus fleas, which were prevalent even in the city centre. More importantly, peridomestic rodents clearly supported the life cycle of ticks in the city as hosts for their subadult stages. In addition to trapping location, season, host species, body condition and host sex, infestation with fleas, gamasid Laelapidae mites and prostigmatic Myobiidae mites were associated with significantly altered abundance of I. ricinus larvae on mice and voles. Whether this is caused by predation, grooming behaviour or interaction with the host immune system is unclear. The present study constitutes a basis to identify interactions and vector function of rodent-associated arthropods and their potential impact on zoonotic diseases

Rozpoloceni loajalitou? - Vliv ruské měkké síly v estonské Narvě uprostřed rusko-ukrajinské války

The city of Narva is Estonia's third largest city, located on the border to Russia. Its inhabitants are largely of Russian origin and many ties to the neighbouring Russia to the east are still existent. When Russia invaded Ukraine for the first time in 2014, breaching the sovereignty of an independent nation, various scholars, journalists, and experts were quick to identify parallels with other geostrategic locations that seemingly resemble the Ukrainian case. For Estonia, the scenario of 'Narva next?' was created. The large proportion of Russophones, economic problems, the legacy of the Soviet oppression and exploitation as well as a societal gap between Estonians and Narvians seemed to make Narva an entry point for Russia's 'green men'. In 2022, Russia is invading Ukraine in a large-scale war, once again showing the violent character of Putin's expansionist ideology. Together with the fear of invasion in the Baltic States, Narva is once again in the spotlight. The Russian influence in NATO and EU member countries is largely exerted through disinformation campaigns, propagated through various media outlets. This dissertation analyses the impact of Russian soft power, both in media, traditions, and cultural ties. The comparison between before and after the invasion of Ukraine on February 24, 2022,...Katedra bezpečnostních studiíDepartment of Security StudiesFakulta sociálních vědFaculty of Social Science
